- Using activity theory and causal diagrams for designing multiagent systems that assist human activities(Springer Verlag, 2013-11-30) Brena, Ramon; Ceballos Cansino, Héctor Gibrán; García Vázquez, Juan Pablo; Instituto Tecnológico y de Estudios Superiores de MonterreyIn this paper, we propose to use the Activity Theory and causal diagrams for modelling human activities with the aim of facilitating the specification of an agent-based assistance system through the Prometheus methodology. As a case study, we consider the elder medication activity, a recurring, complex and context-rich activity that involves several individual and collective activities which may require assistance. From the data collected in a contextual study of the elder medication, we modeled the medical consultation and refill medicine activities. Our results demonstrate that causal diagrams allow to capture the dynamics of the modelled activity, introduce the assistance of intelligent agents, extract the multiple scenarios synthesized in the activity structure and translate them into Prometheus artifacts.
- A hybrid local-global approach for handling ontologies in a multiagent system(2004-06-24) Brena, Ramon; Ceballos Cansino, Héctor Gibrán; Instituto Tecnológico y de Estudios Superiores de MonterreyAs Ontologic knowledge gets more and more important in agent-based systems, its handling becomes crucial for successful applications. We propose a hybrid approach, in which part of the ontology is handled locally, using a "client component", and the rest of the ontological knowledge is handled by an "ontology agent", which is accessed by the other agents in the system through their client component. We propose specific methods for representing, storing, querying and translating ontologies for effective use in the context of the "JITIK" system, which is a multiagent system for knowledge and information distribution. We report as well a working prototype implementing our proposal.
- Combining global and local ontology handling in a multiagent system(IEEE Computer Society, 2004-05-19) Brena, Ramon; Ceballos Cansino, Héctor Gibrán; Instituto Tecnológico y de Estudios Superiores de MonterreyOntologic knowledge is getting more and more important in agent-based systems, and its handling is becoming crucial for successful applications. But placing all the ontology-handling capabilities in each of the system's agents could make them too heavy. We propose a combination of local and global ontology handling, where part of the ontology is handled locally, using a "client component", and the rest of the ontological knowledge is handled by an "ontology agent", which is accessed by the other agents in the system through their client component. We propose specific methods for representing, storing, querying and translating ontologies for effective use in the context of the "JITIK" system, which is a multiagent system for knowledge and information distribution. We report a working prototype implementing our proposal.
- Finding compromises between local and global ontology querying in multiagent systems(Springer Verlag, 2004) Ceballos, Hector; Brena, Ramon; Instituto Tecnológico y de Estudios Superiores de MonterreyAs Ontologie knowledge gets more and more important in agent-based systems, its handling becomes crucial for successful applications. In the context of agent-based applications, we propose a hybrid approach, in which part of the ontology is handled locally, using a "client component", and the rest of the ontological knowledge is handled by an "ontology agent", which is accessed by the other agents in the system through their client component. In this sort of "caching" scheme, most frequent ontologie queries tend to remain stored locally. We propose specific methods for representing, storing, querying and translating ontologies for effective use in the context of the "JITIK" system, which is a multiagent system for knowledge and information distribution. We report as well a working prototype implementing our proposal, and discuss some performance figures.
